i MOTOR-DRIVER' BRUSH.

Application led September 22, 1926. Serial No 137,094.

The object of this invention, is to provide a brush for use upon brushing clothing, but adapted for use, so far as the operative means are concerned, .for various other purposes.

:sl A further object is to provide driving means and mounting means adapted' for use in connection with brushes designed for many diferent purposes, such as manicuring'and shampooing, or substantially any purpose to which a motor driven Lbrush may conveniently be applied. A further object is" to providefa construction in which a twoart brush may be mounted ooncentrically w1th reference to the shaft 15` of the motorrftl'le elements of the two-part brush being removable, if desired, when the operator wlshes to mount an element to be rotated directly on the armature shaft of themotor. i

` A; further object is to provide special means for mounting the motor, these means including a forked frame and handle, lone element of the frame being movablewith reference to the other when one end of the motor shaft is to be left free.

With the foregoing and other objects view, theinvention consists in the n'ovelconf struction and arrangement of 'elements described, illustrated and claimed, `it beingunderstood that modifications maybe made within\`the yscope of the claim lwithout departing from the spirit of the invention.`

In the drawings `forming part of this applicatio, l"

Figure 1 is a view of the device in elevation, showing the brush mounting means carried by a long handle.

0 n f 1 F1 re 2 1s a view 1n vertlcal section showing t e brush mounting meansl carried by a short handle. l

Figure 3 is a 4view -in elevation showing one-arm of the .fork for' mounting the rotary element, swung to a position where it overlies the'otherarm of the fork, so that the elementdriven in this case from the armature shaft, ,maybe'entirely free for use,

Figure 4 is'a `y fragmentary view in elevationof a portion of the forked frame, showing how one end of the motor shaft may be free from the fork;

Figure 6 is a section transversely of the main axis of the brush.

Figure 7 is temeon showing along man' with a portion thereofA broken away, `and The brush structure, and means therefor include the end members 26 100v Figure 5 shows the brush in end elevation.

element'll may however be secured in a'lixed position by means of a thumbscrew 16.d This P construction permits the frame mounting the motor and brush to be employed as in Figure 1, vor as in Figure 3, wherein the element 11 has been swun to a position where it lie's` alongside of e ement 10, so that one end of the armature shaft is free and may mount 75 an element 18 such as a massaging device, or a form' of .brush differing from that of the other views,and may in fact mount any element to be rotated 'in this class of machines or appliancesf .Element 11 of the forked frame 80 is provided with Va notch 11.v adapted to receive the end of the armature shaft,i when the parts are in the position of Figures 2 and 4, butthe shaft may be released from the notch f by releasing plate 21, so that, the elements of the frame may be caused to assume the position of Figure 3. Element 10 of the forked frame is provided with a lateral extension, which ma be termed a boss, and whichis designate 23. The conductors for the motor lmay lead'through this element 23 and through element 10, if desired, and may also extend through shank portion 15, but on the other hand the conducting wires may be otherwise' applied and may extend through the long handle 25 when employed or may extend partly outsideof the handle, in accordance with well known practice.'

the mounting and 27 each having a hub portion, the hub of element-26 beingfcarried by the portion 23 of element 10, whereas end member 27 is provided with a hub directly mounted on Vthe armature shaft 30 of the motor shown con- 105 ventionally at 31. f L

The brush 35 includes a type of brush back comprising segmental' elements 36 and 37 se.- cured by screws such as 38' to the end members 26 and 27. -These elements' 36 and 37 110 n housin including the main portion fits tightly threover.

are Vlan ed as 'shown 'in Fi re 2 andare mounte as illustrated. Fie d' magnetsfor the motor are shown .conventionally at 39.

The A'motor 'is providedl with a two-Eart 40 ing-hu 41 to be secured to the element 23 of elementv 10- and the cap plate or coverof the housing, designated 43, isapertured for the armature sha-ft 30, and is secured to the main portion offthe motor' housing 4 0,ior

1 In irlew of the construction specified, brush 35 including thesegmental backs 36 and 37 may be removed, and likewise the end memfbers 26 and 27 so that the motor may be employedas in Figure .3, the outer end of the armature shaft 30 being free.

Reference hasl been made to the fact that a'lon handle or a short handle may be employe and the conducting wires may extend'through"` or partlyi through the handle.V

Terminal connections including elements detachable from each other, and retained in part by internally threadedcollar 45, are shown in the lower portion of Figure 2 The elenient 45 is rotatable and has threaded connection with member 15 and abuts block 0r plug 46, permittin the terminal pins l to be carried away from t e stationary contacts 48, for breaking the circuit through claimed is: l 'i n in a device of the kind described, a handle,

hayinglat one end two spaced elements forming a fork,vone of said 'elements being rigid` with the handle and the other element kmountf ed on the fixedelement to rotatel about the, axis of the handle, saidjfixed element having` Inounted thereon'a motor and housing ther'ej for,the shaft of the motor having aiifextension beyond-'the housing ori'nounting in rotatable element, and a brush hdetachably connected to'said'extension. i
